  • This application is directed to a system for the management and routing of optical fiber cables.
  • optical fibers for signal transmissions
  • optical fiber cable management requires industry attention.
  • optical fiber management is necessary is the routing of optical fibers from one piece of optical fiber equipment to another.
  • optical fiber cables may be routed between fiber distribution equipment and optical line terminating equipment.
  • the cable routing can take place in concealed ceiling areas or in any other manner to route cables from one location to another.
  • any routing system When routing optical fibers, it is desirable that any routing system will be readily modifiable and adaptable to changes in equipment needs. Accordingly, a routing system which would require a high capital outlay and which could not be readily adapted to changes in a customer's needs is not practical. Namely, if routing paths, once established, are forever fixed, the system cannot adapt. Also, and perhaps most important, any routing system must protect optical fibers from damage.
